Air conditioning system for vehicle}

The present invention relates to an air conditioning system for a vehicle, and more specifically, the present invention uses an integrated heat exchanger in which low-temperature and high-temperature coolant is selectively supplied by a supply valve to exchange heat, thereby simplifying the overall configuration and easily cooling the air-conditioning wind. The purpose is to provide an air conditioning system for vehicles that can provide heating and dehumidification.

In general, a heat exchanger is a device that is installed on a specific flow path and performs heat exchange by allowing the heat exchange medium circulating inside the heat exchanger to absorb heat from outside air or dissipate its own heat to the outside.

These heat exchangers include condensers and evaporators that use refrigerant as a heat exchange medium, radiators and heater cores that use coolant as a heat exchange medium, and oil that uses oil as a heat exchange medium to cool the oil flowing inside the engine and transmission. They are manufactured in a variety of ways depending on the purpose and use, such as coolers.

In recent years, as global interest in the environment and energy has increased in the automobile industry, research has been conducted to improve fuel efficiency, and research and development for weight reduction, miniaturization, and high functionality are continuously conducted to satisfy the needs of various consumers. .

However, in the case of heat exchangers used in automobiles, if multiple heat exchangers are manufactured and installed separately, not only does the manufacturing process increase, resulting in low productivity, but also the waste of materials increases, increasing the cost and securing space to install each heat exchanger. There were also difficulties in doing so. Therefore, in order to solve this problem, various technologies for integrating a plurality of heat exchangers have been developed and used.

As a prior art related to this, an integrated heat exchanger is disclosed as Korean Patent Publication (10-2007-0081635), and Figure 1 is a diagram showing a conventional integrated heat exchanger.

As shown, the conventional integrated heat exchanger includes a plurality of first tubes 11 through which the first fluid flows, a first heat dissipation fin 12 interposed between the first tubes 11, and the first tube 11. A first core portion (10) consisting of first headers (13) each coupled to both ends of a plurality of second tubes (21) through which the second fluid circulates, sandwiched between the second tubes (21). A second core portion 20 consisting of a second heat dissipation fin 22 and a second header 23 respectively coupled to both ends of the second tube 21, and the first and second core portions 10 arranged vertically. ) A single tank 30 that is simultaneously coupled to the first header 12 and the second header 22 of 20 to form a space in which the first and second fluids flow, and the interior of the tank 30 It includes at least one baffle 60 that is installed to separate the first fluid and the second fluid. In this way, the conventional integrated heat exchanger divides the inside of the single tank 30 with a baffle 60 to cool two heat exchange media simultaneously.

However, in this case, in the integrated heat exchanger, two heat exchange media with different temperatures circulate inside a tank partitioned by a baffle (60). At this time, since the two areas divided by the baffle 60 do not change, both areas are designed to be sized to secure maximum cooling capacity so that each heat exchange medium can be cooled according to various vehicle environments. There is a problem that needs to be resolved. In other words, the size of the entire integrated heat exchanger must be increased, otherwise the cooling performance of the heat exchange medium will inevitably deteriorate.

The coolant heated while passing through the condenser 2200 passes through the battery module 1200 and the electrical components 1300. While heating, the air conditioning wind is supplied to the entire first and second heat exchange parts of the integrated heat exchanger (H) through the supply valve 800 to heat the vehicle interior. At this time, the refrigerant that has passed through the evaporator 2400 is bypassed through the bypass line 1600, and is controlled by the second control valve 1520 so that the coolant is not cooled by the radiator 1100. Flow is blocked.

Figure 18 shows an example where the heating unit is the battery module 1200 and the electrical component 1300 when the heating degree is low. That is, in an example in which the refrigerant is not circulated in the refrigerant circulation line 2000, and the coolant heated while passing through the battery module 1200 and the electrical components 1300 is supplied to the integrated heat exchanger (H) to perform heating. indicated. In Figure 18, an example is shown in which heated coolant passes through the battery module 1200 and is transferred to the first heat exchanger through the coolant circulation line 1000 in communication with the evaporator 2400. That is, the coolant heated by the battery module 1200 is supplied to the first heat exchanger, and the coolant heated by the electrical component 1300 is supplied to the second heat exchanger by the second control valve 1520. .

Additionally, although not shown, the coolant circulation line 1000 in communication with the evaporator 2400 is closed, and the coolant heated through the battery module 1200 and the electrical components 1300 is controlled by the second control valve 1520. It is transferred through the coolant circulation line 1000 located at the bottom of the drawing, and is supplied to the first heat exchanger and the second heat exchanger, and then can be transferred back to the battery module 1200 and the electric component 1300. .

Additionally, the coolant is cooled while passing through the evaporator (2400) and cooled while passing through the radiator (1100) while passing through the electrical components (1300).

Meanwhile, the heater core 1400 indicated by number 1400 may be provided on the coolant circulation line 1000 to control the temperature of the battery module 1200.

That is, as described above, the vehicle air conditioning system (S) of the present invention performs cooling by receiving a low-temperature first heat exchange medium through the supply valve 800, or performs heating by receiving a high-temperature second heat exchange medium. Alternatively, dehumidifying cooling can be performed by receiving the first and second heat exchange media, respectively, and there is an advantage in that the battery module 1200 and the electrical components 1300 can be selectively cooled or heated.

The present invention is not limited to the above-described embodiments, and its scope of application is diverse, and anyone skilled in the art can understand it without departing from the gist of the invention as claimed in the claims. Of course, various modifications are possible.
